没有找到Javac - 已经为PATH添加了bin

Question

尽管将其位置添加到PATH变量，我仍无法使javac工作。错误如下：

me@comp-LTW ~
$ javac
-bash: javac: command not found

下面

PATH：

$ echo $PATH
/jre/bin:/usr/local/bin:/usr/bin:/cygdrive/c/ProgramData/Oracle/Java/javapath:/cygdrive/c/Program Files (x86)/OpenSSH/bin:/cygdrive/c/Program Files (x86)/Symantec/VIP Access Client:/cygdrive/c/Program Files (x86)/Skype/Phone:/cygdrive/c/Program Files (x86)/apache-maven-3.3.9/bin: C:/cygwin64/bin:/cygdrive/c/Program Files (x86)/sbt/bin: C:/Program Files/Java/jdk1.8.0_112/bin: /cygdrive/c/Program Files/Java/jdk1.8.0_112/bin:/cygdrive/c/texlive/2016/bin/win32:/cygdrive/c/Users/anyoung/AppData/Local/Box/Box Edit: C:/Program Files/Java/jdk1.8.0_112/bin:/usr/lib/lapack

我已阅读以下内容：

How to tell if JRE or JDK is installed

目标是查看我是否已成功安装JDK。以下内容似乎显示JRE的版本，而不是JDK。

$ java -version
java version "1.8.0_112"
Java(TM) SE Runtime Environment (build 1.8.0_112-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.112-b15, mixed mode)

在cmd：
